In a cathode ray tube, electrons are accelerated from rest by a constant electric force of magnitude 6.40 × 10−17 N during the first 4.40 cm of the tube’s length; then they move at essentially constant velocity another 45.0 cm before hitting the screen.

a.How long does it take them to travel the length of the tube?

b.Find the speed of the electrons when they hit the screen.

c.How long does it take them to travel the length of the tube?

The electrons in a cathode ray tube are emitted by a hot filament cathode and are accelerated by an electric field applied between the cathode and two orthogonal pairs of parallel plate electrodes. The beam passes through the gap between the electrodes and can be deflected up and down, or left and right if the parallel plates are appropriately biased. As the electrons pass through the electrodes, their kinetic energy increases. Assume the electrons are emitted from the cathode with...
